Answer: 20%
The alcohol that is swallowed by a person avoids the normal digestive process. It travels down the esophagus into the stomach and the small intestine and goes right into the bloodstream. About 20 percent of the alcohol consumed by the body is absorbed in the stomach, and about 80 percent is absorbed in the small intestine. The liver is the organ that is particularly affected by alcohol because it is the main organ that processes alcohol.
